California has long been a diverse place, starting with the mixture of European Spaniards and Native Americans. Throughout history, many different racial groups have moved to California, though they often faced unfair treatment and discrimination, as seen in the anti-Chinese movements and internment of Japanese Americans during World War II. Today, California remains highly diverse, with the 2000 census finding that over 40% of the state's population is Hispanic, Asian, or from Central or South America.
